Some doubts still exist as to whether there are two distinct species, 

 HooJceriana and Pattoniana, as MacNab states loc. cit. , or whether 

 both form one species. The leaf-structure is essentially the same as 

 in other Tsugas. The flat-leaved form with stomata on the lower 

 surface only, grown in some gardens under this name {Pattoniana), is 

 presumed by Engelmann to be a form of T. Mertensiana. See Gard. 

 Chron. April 4, 1882. Engelmann and, recently on anatomical grounds, 

 Van Tieghem consider T. Pattoniana as the representative of a separate 

 section or even genus, having leaves almost tufted, not distichous, 

 convex, keeled on the upper surface, acutish, stomatose on both sides ; 

 pollen grains bilobed ; cones larger than in Tsuga proper ; the scales 

 recurved at the tips. Lemmon also makes the plant the representa- 

 tive of a distinct genus.

 Brongniart. (Tribe Cupressine^.) 



A genus of South African trees, differing from the Australian 

 Callitris which they much resemble in having spirally disposed leaves 

 and numerous seeds to each scale of the cone. 



The species named are W. juniperoides, W. Commersoni 

 and W, cupressoides, representatives of which, or plants so named, 

 are met with in Botanic gardens, under glass. Some forms of 

 Retinospora (which see) are also loosely called Widdringtonias. 

 W. glauca of Gordon's Herbarium (MSS.) is Fitzroya patagonica.
